(MAC users just click the link and hold down on the mouse button)

In Internet Explorer Choose "Save Target As..." and download the file to your desktop (in Netscape you choose "Save Link As..").  

Perform the same download steps for each of the bonuses also.

Once you select "save target as" or "save link as" a download screen will come up asking you where you want to save the file to on your computer.

You should save the files to your "Desktop" or another folder you can easily find. Once you have downloaded the file, go to your desktop or the folder you saved it to and double click the file to open it. This should launch Adobe Acrobat Reader and automatically display the ebook.
